Inflammation involves the activation of the immune system in response toharmful stimuli, such as, e.g., a pathogen, infection, irritant, ordamage to cells. As a stereotyped response, inflammation is a mechanismof innate immunity, as compared to adaptive immunity, which is specificfor each pathogen.

Inflammation can be classified as either acute or chronic. Generallyspeaking, acute inflammation is mediated by granulocytes, while chronicinflammation is mediated by mononuclear cells such as monocytes andlymphocytes.

Acute inflammation is an initial protective response of the body toremove an injurious stimulus by maintaining tissue integrity andcontributing to tissue repair. It a part of the body's natural defensesystem against injury and disease, and in the absence of acuteinflammation, wounds and infections would never heal and progressivedestruction of the tissue would compromise the survival of the organism.

The process of acute inflammation is initiated by cells already presentin all tissues, mainly resident macrophages, dendritic cells,histiocytes, Kupffer cells, mastocytes, vascular endothelial cells, andvascular smooth muscle cells. At the onset of a harmful stimulus, thesecells undergo activation and release inflammatory mediating andsensitizing molecules, such as, e.g., pro-inflammatory cytokines,pro-inflammatory prostaglandins, leukotrienes, histamine, serotonin,neutral proteases, bradykinin and nitric oxide. These inflammatorymolecules modulate a complex series of biological events involvingcellular and acellular components of the local vascular system, theimmune system, and the injured tissue site to propagate and mature theinflammatory response. These events are responsible for eliciting anacute inflammatory response, typically characterized by 1)vasodilatation which increases blood flow into the tissue therebycausing erythema (redness and warmth), which may extend beyond this site(the flare response); 2) blood vessel permeability which increasesplasma leakage into the tissue thereby causing edema (swelling); 3)alter the excitability of certain sensory neurons causinghypersensitivity and pain; 4) stimulate the release of inflammationinducing molecules such as, e.g., neuropeptides like substance P (SP)and calcitonin gene-related peptide (CGRP), prostaglandins, and aminoacids like glutamate, from the peripheral nerve endings; and 5) increasemigration of leukocytes, mainly granulocytes, from the blood vesselsinto the tissue. An acute inflammatory response requires constantstimulation to be sustained and must be actively terminated when nolonger needed. Hence, acute inflammation ceases once the injuriousstimulus has been removed.

However, severe or prolonged noxious stimulation results in a chronicinflammatory response that leads to a progressive shift in the type ofcells present at the site of tissue injury. Chronic inflammation may becharacterized as the simultaneous destruction and healing of tissue fromthe inflammatory process, with the net result of provoking injury ratherthan mediating repair. As such, chronic inflammation is a disease. As aninflammatory response can occur anywhere in the body, chronicinflammation has been implicated in the pathophysiology of a wide rangeof seemingly unrelated disorders which underlay a large and varied groupof human diseases. For example, chronic inflammation is involved indiseases as diverse as cardiovascular diseases, cancers, allergies,obesity, diabetes, digestive system diseases, degenerative diseases,auto-immune disorders, and Alzheimer's disease.

Attempts to treat chronic inflammation have met with limited success.This is due, in part, to the fact that the etiology of chronicinflammation is a complex response based in part on the variousinflammation inducing molecules and the multitude of inflammationmediating and sensitizing molecules that appear to elicit inflammationvia redundant mechanism. In addition, besides blocking pro-inflammatorymolecules, many anti-inflammatory drugs, also inhibit regulatory loopsthat release endogenous anti-inflammatory molecules. For example, NSAIDsreduce inflammation by blocking the enzymatic activity ofcyclooxygenase, a key enzyme that catalyzes the conversion ofarachidonic acid to prostaglandins and leukotrienes. Thus, NSAIDs reduceinflammation by preventing the synthesis of all prostaglandins. However,NSAIDs not only prevents the synthesis of proinflammatoryprostaglandins, these compounds also prevent the synthesis ofanti-inflammatory prostaglandins. Hence, NSAIDs have limited success asthey block endogenous anti-inflammatory response, which in someinstances may prolong chronic inflammation. Therefore, compounds,compositions, uses, and methods preferentially inhibitingpro-inflammatory responses would be highly desirable for the treatmentof chronic inflammation.

The pharmaceutical compositions disclosed herein areformulated in a manner that essentially produces a lipid-adjuvantdelivery system that enables a therapeutic compound havinganti-inflammatory activity to be delivered in a manner that moreeffectively inhibits a pro-inflammatory response.

DESCRIPTION

The present specification discloses solid solution compositions usefulto formulate a wide variety of therapeutic compounds. Solid solutioncompositions are crystalline solids comprising a matrix of a solventmaterial (which may be solid at normal temperatures) and solutes wherethe molecules in the solid solution are arranged in a random fashion andnot in an ordered alignment. The solid solution pharmaceuticalcompositions disclosed herein act as a delivery system that enable atherapeutic compound disclosed herein to be more effectively deliveredor targeted to a cell type, tissue, organ, or region of the body in amanner that more effectively inhibits a pro-inflammatory response. Thisinhibition results in an improved treatment of a chronic inflammation.

For example, a pharmaceutical composition disclosed herein mayfacilitate the delivery of a therapeutic compound disclosed herein intomacrophages. Macrophages exist at the crossroads of two fundamentalpathways being the principle cells in the immune system and also lipidmetabolism. With regards to the immune system, most pathogens have alipid-containing surface component that macrophage recognize and thenengulf the pathogen. One possible mechanism that achieves this selectivebiodistribution is that the pharmaceutical compositions disclosed hereinmay be designed to take advantage of the activity of chylomicrons.Chylomicrons are relatively large lipoprotein particles having adiameter of 75 nm to 1,200 nm. Comprising triglycerides (85-92%),phospholipids (6-12%), cholesterol (1-3%) and apolipoproteins (1-2%),chylomicrons transport dietary lipids from the intestines to otherlocations in the body. Chylomicrons are one of the five major groups oflipoproteins, the others being VLDL, IDL, low-density lipoproteins(LDL), high-density lipoproteins (HDL), that enable fats and cholesterolto move within the water-based solution of the bloodstream.

During digestion, fatty acids and cholesterol undergo processing in thegastrointestinal tract by the action of pancreatic juices includinglipases and emulsification with bile salts to generate micelles. Thesemicelles allow the absorption of lipid as free fatty acids by theabsorptive cells of the small intestine, known as enterocytes. Once inthe enterocytes, triglycerides and cholesterol are assembled intonascent chylomicrons. Nascent chylomicrons are primarily composed oftriglycerides (85%) and contain some cholesterol and cholesteryl esters.The main apolipoprotein component is apolipoprotein B-48 (APOB48). Thesenascent chylomicrons are released by exocytosis from enterocytes intolacteals, lymphatic vessels originating in the villi of the smallintestine, and are then secreted into the bloodstream at the thoracicduct's connection with the left subclavian vein.

While circulating in lymph and blood, chylomicrons exchange componentswith HDL. The HDL donates apolipoprotein C-Ill (APOC2) andapolipoprotein E (APOE) to the nascent chylomicron and thus converts itto a mature chylomicron (often referred to simply as “chylomicron”).APOC2 is the cofactor for lipoprotein lipase (LPL) activity. Oncetriglyceride stores are distributed, the chylomicron returns APOC2 tothe HDL (but keeps APOE), and, thus, becomes a chylomicron remnant, nowonly 30-50 nm. APOB48 and APOE are important to identify the chylomicronremnant in the liver for endocytosis and breakdown into lipoproteins(VLDL, LDL and HDL). These lipoproteins are processed and stored bycompetent cells, including, e.g., hepatocytes, adipocytes andmacrophages. Thus, without wishing to be limited by any theory, uponoral administration, a pharmaceutical composition disclosed herein canbe processed into micelles while in the gastrointestinal tract, absorbedby enterocytes and assembled into nascent chylomicrons, remainassociated with chylomicron remnants taken up by the liver, andultimately loaded into macrophages which are present in inflamedtissues.

As another example, a pharmaceutical composition disclosed herein mayfacilitate the delivery of a therapeutic compound disclosed herein intodentritic cells. One possible mechanism to achieve selectivebiodistribution of the pharmaceutical compositions disclosed herein maybe to take advantage of the endocytotic/phagocytotic activity ofdentritic cells. Dendritic cells are immune cells forming part of themammalian immune system. The main function of dendritic cells is toprocess antigen material and present it on the surface to other cells ofthe immune system. Thus, dendritic cells function as antigen-presentingcells that act as messengers between innate and adaptive immunity.Dendritic cells are present in tissues in contact with the externalenvironment, such as, e.g., the skin (where there is a specializeddendritic cell type called Langerhans cells) and the inner lining of thenose, lungs, stomach and intestines. These cells can also be found in animmature state in the blood. Once activated, they migrate to the lymphnodes where they interact with T cells and B cells to initiate and shapethe adaptive immune response. Dendritic cells are known to endocytoseand phagocytose lipid particles as part of their environmentalmonitoring and antigen presentation processes. Without wishing to belimited by any theory, upon topical or inhalatory administration, apharmaceutical composition disclosed herein can penetrate into the skinor inner lining of the nose, lungs, stomach and intestines, beendocytosed/phagocytosed by dendritic cells, and ultimately loaded intoT cells and/or B cells which are present in inflamed tissues.

In addition to the targeted delivery of the therapeutic compounddisclosed herein, a solid solution pharmaceutical composition disclosedherein take advantage of the different melting point temperatures of thevarious lipids used. By controlling the types and amounts of the lipidsadded, a pharmaceutical composition disclosed herein can be made that issubstantially solid at room temperature, but melts when it reaches bodytemperature, such as, e.g., after being ingested. The resulting meltedcomposition readily forms micelles which are absorbed by the intestine,assembled into chylomicrons, and ultimately absorbed by macrophages ortaken up by dentritic cells as described above.

Aspects of the present specification disclose, in part, a solid solutioncomposition. A solid solution composition disclosed herein is generallyadministered as a pharmaceutical acceptable composition. As used herein,the term “pharmaceutically acceptable” refers any molecular entity orcomposition that does not produce an adverse, allergic or other untowardor unwanted reaction when administered to an individual. As used herein,the term “pharmaceutically acceptable composition” is synonymous with“pharmaceutical composition” and means a therapeutically effectiveconcentration of an active ingredient, such as, e.g., any of thetherapeutic compounds disclosed herein. A pharmaceutical compositiondisclosed herein is useful for medical and veterinary applications. Apharmaceutical composition may be administered to an individual alone,or in combination with other supplementary active ingredients, agents,drugs or hormones.

To influence the pharmacodynamics of a therapeutic compound disclosedherein three features of the solid solution composition must be present.First, at least one lipid used in the solid solution composition must bemade up of at least one fatty acid in which the carbon chain length isabove 12 and below 24 and therefore suitable for absorption through theenterocyte pathways. Fatty acids below this C₁₂-C₂₄ length do not form alipid-drug matrix, and thus the drug is taken up by the body by thenormal absorption process. Fatty acids above this C₁₂-C₂₄ length,although forming lipid-drug matrices, cannot be absorbed and the drugleaches out of the solid solution composition and is eliminated by thebody via the gastrointestinal tract.

Second, the therapeutic compound itself should have a lipohilicity thatallows it to form a solid solution matric with the C₁₂-C₂₄ lipid. Asdiscussed below, this lipohilicity can be inherent to the therapeuticcompound (lipid-soluble drug formulations), or certain additives may beused that facilitate a wider range of lipid soluble drugs in the matrix(free acid/free base drug formulations, salt drug formulations, andcombination drug formulations).

Third, the therapeutic compound itself should influence the biology ofcertain cell types that are contacted by the lipid-adjuvant nature of asolid solution composition that ultimately circulate in the body. Suchconstructs include chylomicron, LDL particles and HDL particles. Thecell types contacted may include macrophages, dendritic cells andadipose cells and cancer cells. Tissues that have a high surface lipidcontent may also be preferentially targeted. These include nerve tissuesand the brain.

The present specification discloses four general types of solid solutioncompositions, namely lipid-soluble drug formulations, free acid/freebase drug formulations, salt drug formulations, and combination drugformulations. Solid solution compositions formulated using alipid-soluble drug formulation only require a lipid component toformulate a therapeutic compound disclosed herein into a solid solutioncomposition. Without wishing to be limited by a theory, lipid-solubledrugs can typically be dissolved in a lipid under heat. Upon cooling itis believed that the lipid component and drug form lipid-drug matricesorganized in a manner where the lipids encase the drug. Since onlyhydrophobic interactions are present, there is no organized alignment ofthese lipid-drug matrices resulting in a solid solution composition(i.e., there is no crystallization into a classic solid form).

Generally, therapeutic compounds having a log P of about 3.0 or greaterare useful in a lipid-soluble drug formulation. Non-limiting examplesinclude an Artemisinin like Arteether, Artemether, Artemisinin,Artesunate, and Dihydroartemisinin; a Fibrate like Bezafibrate,Ciprofibrate, Clofibrate, Fenofibrate, and Gemfibrozil; and a Statinlike Atorvastatin, Fluvastatin, Lovastatin, Pitavastatin, Pravastatin,Rosuvastatin, and Simvastatin.

A lipid-soluble drug formulation does not use or require a surfactant.In addition, a lipid-soluble drug formulation does not use or requirenon-lipid based solvent.

Solid solution compositions formulated using a free acid/free base drugformulation require a stabilizing agent in addition to a lipid componentto formulate a therapeutic compound disclosed herein into a solidsolution composition. A therapeutic compound having a free acid or freebase can dissolve in a lipid under heat, but upon cooling to roomtemperature will crystalize to form a classic solid composition. Thisoccurs because the thermodynamic properties of these mixtures favor thelower energy solid phase. In order to produce a solid solutioncomposition, a stability agent must be added to stabilize the drug andprevent its transition into a classic solid phase upon cooling. Withoutwishing to be limited by a theory, it is believed that the stabilityagent coats lipid-drug matrices upon their formation. This coatingimpedes interactions between matrices thereby preventing the alignmentsnecessary to form a crystalline matrix of a solid phase composition. Assuch, the transition to a solid phase does not occur and a solidsolution composition is formed. Thus, a stability agents is a compoundthat provide a barrier to the thermodynamic transition to a classicsolid phase or prolongs this transition to such an extent that it doesnot occur. Examples of stability agents include liquid polyethyleneglycols, isosorbide dimethyl ether, diethylene glycol monoethyl ether(2-(2-ethoxyethoxy)ethanol), monohydrate alcohols

Generally, therapeutic compounds having a log P of about 2.2 to about3.0 are useful in a free acid/free base drug formulation. Non-limitingexamples include a non-steroidal anti-inflammatory drug (NSAID) and anester of aminobenzoic acid. A NSAID includes a salicylate derived NSAID,a p-amino phenol derived NSAID, a propionic acid derived NSAID, anacetic acid derived NSAID, an enolic acid (Oxicam) derived NSAID, afenamic acid derived NSAID, a non-selective cyclo-oxygenase (COX)inhibitor, a selective cyclooxygenase 1 (COX 1) inhibitor, a selectivecyclooxygenase 2 (COX 2) inhibitor. An ester of aminobenzoic acidincludes Amylocaine, Benzocaine, Butacaine, Butamben, Chloroprocaine,Dimethocaine, Lidocaine, Meprylcaine, Metabutethamine, Metabutoxycaine,Orthocaine, Prilocaine, Propoxycaine, Procaine (Novocaine),Proxymetacaine, Risocaine, and Tetracaine.

Solid solution compositions formulated using a salt drug formulationrequire a neutralizing agent in addition to a lipid component toformulate a therapeutic compound disclosed herein into a solid solutioncomposition. A therapeutic compound salt can dissolve in a lipid underheat, but upon cooling to room temperature will crystalize to form aclassic solid composition. This occurs because the thermodynamicproperties of these mixtures favor the lower energy solid phase. Inorder to produce a solid solution composition, a neutralizing agent mustbe added to neutralize a therapeutic compound salt and prevent itstransition into a classic solid phase upon cooling. Without wishing tobe limited by a theory, it is believed that the neutralizing agenteliminates that charges presence in the salt drugs. This neutralizationimpedes the ionic interactions between matrices thereby preventing thealignments necessary to form a crystalline matrix of a solid phasecomposition. As such, the transition to a solid phase does not occur anda solid solution composition is formed. Thus, a neutralizing agent is acompound that provide a barrier to the thermodynamic transition to aclassic solid phase or prolongs this transition to such an extent thatit does not occur.

Neutralizing agents include fatty acids for base-salt drugs andtriethanolamine for acid-salt drugs. The degree of neutralizationdepends on the amount of neutralizing agent added to the formulation.For complete neutralization, one molar equivalent of neutralizing agentis added to the formulation. For partial neutralization, less than onemolar equivalent is added. Partial neutralization is advantageous inproducing a sustained release formulation. Upon administration, aportion of the drug is immediately made available to the body (instantbioavailability) while the bioavailability of another portion is delayeduntil the neutralized by the neutralizing agent. A neutralizing agentmay also be added in an excessive amount, i.e., more than one molarequivalent. Besides neutralizing the salt-drug, excessive amounts ofneutralizing agent can also enable adjustments to the melting point ofthe solid solution composition.

Generally, therapeutic compounds having a log P of about 2.2 or less areuseful in a salt drug formulation. Non-limiting examples includeryanodine receptor antagonists like Azumolene and Dantrolene; andAngiotensin II receptor antagonists like Azilsartan, Candesartan,Eprosartan, Irbesartan, Losartan, Olmesartan, Telmisartan, andValsartan.

Solid solution compositions may also comprises different combinations oflipid-soluble drugs, free-acid/free-base drugs, and salt drugs.Depending of the drugs used, such formulations, besides the lipidcomponent and the drug, can also include a stabilizing agent, aneutralizing agent, or both.

Aspects of the present specification disclose, in part, a therapeuticcompound. A therapeutic compound is a compound that providespharmacological activity or other direct effect in the diagnosis, cure,mitigation, treatment, or prevention of disease, or to affect thestructure or any function of the body of man or animals.

Thus, the therapeutic compound disclosed herein maycomprise a R-enantiomer only, a S-enantiomer only, or a combination ofboth a R-enantiomer and a S-enantiomer of a therapeutic compound. Atherapeutic compound disclosed herein may have anti-inflammatoryactivity.

In yet otheraspects of this embodiment, a therapeutic compound disclosed herein hasan anti-inflammatory activity capable of reducing the levels of SP,CGRP, glutamate, or a combination thereof released from a sensory neuronin a range from, e.g., about 10% to about 100%, about 20% to about 100%,about 30% to about 100%, about 40% to about 100%, about 50% to about100%, about 60% to about 100%, about 70% to about 100%, about 80% toabout 100%, about 10% to about 90%, about 20% to about 90%, about 30% toabout 90%, about 40% to about 90%, about 50% to about 90%, about 60% toabout 90%, about 70% to about 90%, about 10% to about 80%, about 20% toabout 80%, about 30% to about 80%, about 40% to about 80%, about 50% toabout 80%, or about 60% to about 80%, about 10% to about 70%, about 20%to about 70%, about 30% to about 70%, about 40% to about 70%, or about50% to about 70%.

Prostaglandins mediate a local inflammatory response and are involved inall inflammatory functions through action on prostaglandin receptors andmediate inflammatory signaling including chemotaxis (macrophages,neutrophils and eosinophils), vasodilation and algesia. However, thePG-mediated inflammatory response is self-limiting (resolving). Theprinciple resolution factor is a prostaglandin called 15dPGJ2, which isan endogenous agonist of peroxisome proliferator-activator receptorgamma (PPAR-γ) signaling. PPARγ signaling pathway 1) induces apoptosisof Macrophage M1 cells, thereby reducing the levels of Th1pro-inflammatory cytokines and 2) promotes differentiation of monocytesinto Macrophage M2 cells. Macrophage M2 cells produce and release Th2anti-inflammatory cytokines.

The peroxisome proliferator-activated receptors (PPARs) are a group ofnuclear receptor proteins that function as transcription factorsregulating the expression of genes. All PPARs are known toheterodimerize with the retinoid X receptor (RXR) and bind to specificregions on the DNA of target genes called peroxisome proliferatorhormone response elements (PPREs). PPARs play essential roles in theregulation of cellular differentiation, development, and metabolism(carbohydrate, lipid, protein), and tumorigenesis of higher organisms.The family comprises three members, PPAR-α, PPAR-γ, and PPAR-δ (alsoknown as PPAR-β). PPAR-α is expressed in liver, kidney, heart, muscle,adipose tissue, as well as other tissues. PPAR-δ is expressed in manytissues but markedly in brain, adipose tissue, and skin. PPAR-γcomprises three alternatively-spliced forms, each with a differentexpression pattern. PPAR-γ1 is expressed in virtually all tissues,including heart, muscle, colon, kidney, pancreas, and spleen. PPAR-γ2 isexpressed mainly in adipose tissue. PPAR-γ3 is expressed in macrophages,large intestine, and white adipose tissue. Endogenous ligands for thePPARs include free fatty acids and eicosanoids. PPAR-γ is activated byPGJ2 (a prostaglandin), whereas PPAR-α is activated by leukotriene B4.

Aspects of the present specification disclose, in part, one or morelipids. A lipid may be broadly defined as a hydrophobic or amphiphilicsmall molecule. The amphiphilic nature of some lipids allows them toform structures such as vesicles, liposomes, or membranes in an aqueousenvironment. Non-limiting examples, of lipids include fatty acids,glycerolipids, phospholipids, sphingolipids, sterol lipids, prenollipids, saccharolipids, and polyketides.

A lipid useful in the pharmaceutical compositions disclosed herein maybe a pharmaceutically-acceptable fatty acid. A fatty acid comprises acarboxylic acid with a long unbranched hydrocarbon chain which may beeither saturated or unsaturated. Thus arrangement confers a fatty acidwith a polar, hydrophilic end, and a nonpolar, hydrophobic end that isinsoluble in water. Most naturally occurring fatty acids have ahydrocarbon chain of an even number of carbon atoms, typically between 4and 24 carbons, and may be attached to functional groups containingoxygen, halogens, nitrogen, and sulfur. Synthetic or non-natural fattyacids may have a hydrocarbon chain of any number of carbon atoms frombetween 3 and 40 carbons. Where a double bond exists, there is thepossibility of either a cis or a trans geometric isomerism, whichsignificantly affects the molecule's molecular configuration. Cis-doublebonds cause the fatty acid chain to bend, an effect that is morepronounced the more double bonds there are in a chain. Most naturallyoccurring fatty acids are of the cis configuration, although the transform does exist in some natural and partially hydrogenated fats andoils.

Another lipid useful in the pharmaceutical compositions disclosed hereinmay be a pharmaceutically-acceptable room temperature liquid lipid. Alsoknown as a “liquid fat”, a room temperature liquid lipid includes anyfatty acid that is liquid at normal room temperature, such as, e.g.about 20° C.

A pharmaceutically-acceptable room temperature liquid lipid includes apharmaceutically-acceptable partially hydrogenated fat. The process ofhydrogenation adds hydrogen atoms to unsaturated lipid, eliminatingdouble bonds and making them into partially or completely saturatedlipid. Partial hydrogenation is a chemical rather than enzymatic, thatconverts a part of cis-isomers into trans-unsaturated lipids instead ofhydrogenating them completely. In the first reaction step, one hydrogenis added, with the other, coordinatively unsaturated, carbon beingattached to the catalyst. The second step is the addition of hydrogen tothe remaining carbon, producing a saturated fatty acid. The first stepis reversible, such that the hydrogen is readsorbed on the catalyst andthe double bond is re-formed. The intermediate with only one hydrogenadded contains no double bond and can freely rotate. Thus, the doublebond can re-form as either cis or trans, of which trans is favored,regardless the starting material.

Aspects of the present specification disclose, in part, use of a solidsolution composition disclosed herein for the treatment of chronicinflammation.

Aspects of the present specification disclose, in part, treating anindividual suffering from a chronic inflammation. As used herein, theterm “treating,” refers to reducing or eliminating in an individual aclinical symptom of a chronic inflammation; or delaying or preventing inan individual the onset of a clinical symptom of a chronic inflammation.For example, the term “treating” can mean reducing a symptom of acondition characterized by a chronic inflammation by, e.g., at least20%, at least 25%, at least 30%, at least 35%, at least 40%, at least45%, at least 50%, at least 55%, at least 60%, at least 65%, at least70%, at least 75%, at least 80%, at least 85%, at least 90% at least95%, or at least 100%. The actual symptoms associated with chronicinflammation are well known and can be determined by a person ofordinary skill in the art by taking into account factors, including,without limitation, the location of the chronic inflammation, the causeof the chronic inflammation, the severity of the chronic inflammation,and/or the tissue or organ affected by the chronic inflammation. Thoseof skill in the art will know the appropriate symptoms or indicatorsassociated with a specific type of chronic inflammation and will knowhow to determine if an individual is a candidate for treatment asdisclosed herein.

Chronic inflammation symptoms include, without limitation, edema,hyperemia, erythema, bruising, tenderness, stiffness, swollenness,fever, chills, stuffy nose, stuffy head, breathing problems, fluidretention, blood clots, loss of appetite, increased heart rate,formation of granulomas, fibrinous, pus, non-viscous serous fluid, orulcer and pain. The actual symptoms associated with a chronicinflammation are well known and can be determined by a person ofordinary skill in the art by taking into account factors, including,without limitation, the location of the inflammation, the cause of theinflammation, the severity of the inflammation, the tissue or organaffected, and the associated disorder.

Specific patterns of chronic inflammation are seen during particularsituations that arise in the body, such as when inflammation occurs onan epithelial surface, or pyogenic bacteria are involved. For example,granulomatous inflammation is an inflammation resulting from theformation of granulomas arising from a limited but diverse number ofdiseases, include, without limitation, tuberculosis, leprosy,sarcoidosis, and syphilis. Purulent inflammation is an inflammationresulting in large amount of pus, which consists of neutrophils, deadcells, and fluid. Infection by pyogenic bacteria such as staphylococciis characteristic of this kind of inflammation. Serous inflammation isan inflammation resulting from copious effusion of non-viscous serousfluid, commonly produced by mesothelial cells of serous membranes, butmay be derived from blood plasma. Skin blisters exemplify this patternof inflammation. Ulcerative inflammation is an inflammation resultingfrom the necrotic loss of tissue from the epithelial surface, exposinglower layers and forming an ulcer.

A chronic inflammation symptom can be associated with a large, unrelatedgroup of disorders which underlay a variety of diseases and disorders.The immune system is often involved with chronic inflammatory disorders,demonstrated in both allergic reactions and some myopathies, with manyimmune system disorders resulting in abnormal inflammation.

A myopathy includes an inflammatory myopathy and an auto-immunemyopathy. Myopathies include, without limitation, dermatomyositis,inclusion body myositis, and polymyositis.

In another embodiment, a chronic inflammation comprises a vasculitis.Vasculitis is a varied group of disorders featuring inflammation of avessel wall including lymphatic vessels and blood vessels like veins(phlebitis), arteries (arteritis) and capillaries due to leukocytemigration and resultant damage. The inflammation may affect any sizeblood vessel, anywhere in the body. It may affect either arteries and/orveins. The inflammation may be focal, meaning that it affects a singlelocation within a vessel; or it may be widespread, with areas ofinflammation scattered throughout a particular organ or tissue, or evenaffecting more than one organ system in the body. Vasculitis include,without limitation, Buerger's disease (thromboangiitis obliterans),cerebral vasculitis (central nervous system vasculitis), Churg-Straussarteritis, cryoglobulinemia, essential cryoglobulinemic vasculitis,giant cell (temporal) arteritis, Golfer's vasculitis, Henoch-Schonleinpurpura, hypersensitivity vasculitis (allergic vasculitis), Kawasakidisease, microscopic polyarteritis/polyangiitis, polyarteritis nodosa,polymyalgia rheumatica (PMR), rheumatoid vasculitis, Takayasu arteritis,Wegener's granulomatosis, and vasculitis secondary to connective tissuedisorders like systemic lupus erythematosus (SLE), rheumatoid arthritis(RA), relapsing polychondritis, Behçet's disease, or other connectivetissue disorders, vasculitis secondary to viral infection.

In another embodiment, a chronic inflammation comprises a cardiovasculardisease. When LDL cholesterol becomes embedded in arterial walls, it caninvoke an immune response. Chronic inflammation eventually can damagethe arteries, which can cause them to burst. Cardiovascular disease isany of a number of specific diseases that affect the heart itself and/orthe blood vessel system, especially the veins and arteries leading toand from the heart. There are more than 60 types of cardiovasculardisorders including, without limitation, a hypertension, endocarditis,myocarditis, heart valve dysfunction, congestive heart failure,myocardial infarction, a diabetic cardiac conditions, blood vesselinflammation like arteritis, phlebitis, vasculitis; arterial occlusivedisease like arteriosclerosis and stenosis, inflammatory cardiomegaly, aperipheral arterial disease; an aneurysm; an embolism; a dissection; apseudoaneurysm; a vascular malformation; a vascular nevus; a thrombosis;a thrombphlebitis; a varicose veins; a stroke. Symptoms of acardiovascular disorder affecting the heart include, without limitation,chest pain or chest discomfort (angina), pain in one or both arms, theleft shoulder, neck, jaw, or back, shortness of breath, dizziness,faster heartbeats, nausea, abnormal heartbeats, feeling fatigued.Symptoms of a cardiovascular disorder affecting the brain include,without limitation, sudden numbness or weakness of the face, arm, orleg, especially on one side of the body, sudden confusion or troublespeaking or understanding speech, sudden trouble seeing in one or botheyes, sudden dizziness, difficulty walking, or loss of balance orcoordination, sudden severe headache with no known cause. Symptoms of acardiovascular disorder affecting the legs, pelvis and/or arm include,without limitation, claudication, which is a pain, ache, or cramp in themuscles, and cold or numb feeling in the feet or toes, especially atnight.

In another embodiment, a chronic inflammation comprises a cancer.Inflammation orchestrates the microenvironment around tumors,contributing to proliferation, survival and migration. For example,fibrinous inflammation results from a large increase in vascularpermeability which allows fibrin to pass through the blood vessels. Ifan appropriate procoagulative stimulus is present, such as cancer cells,a fibrinous exudate is deposited. This is commonly seen in serouscavities, where the conversion of fibrinous exudate into a scar canoccur between serous membranes, limiting their function. In anotherexample, a cancer is an inflammatory cancer like a NF-κB-driveninflammatory cancer.

In another embodiment, a chronic inflammation comprises apharmacologically-induced inflammation. Certain drugs or exogenicchemical compounds are known to affect inflammation. For example,Vitamin A deficiency causes an increase in an inflammatory response.Certain illicit drugs such as cocaine and ecstasy may exert some oftheir detrimental effects by activating transcription factors intimatelyinvolved with inflammation (e.g. NF-κB).

In another embodiment, a chronic inflammation comprises an infection. Aninfectious organism can escape the confines of the immediate tissue viathe circulatory system or lymphatic system, where it may spread to otherparts of the body. If an organism is not contained by the actions ofacute inflammation it may gain access to the lymphatic system via nearbylymph vessels. An infection of the lymph vessels is known aslymphangitis, and infection of a lymph node is known as lymphadenitis. Apathogen can gain access to the bloodstream through lymphatic drainageinto the circulatory system. Infections include, without limitation,bacterial cystitis, bacterial encephalitis, pandemic influenza, viralencephalitis, and viral hepatitis (A, B and C).

In another embodiment, a chronic inflammation comprises a tissue ororgan injury. Tissue or organ injuries include, without limitation, aburn, a laceration, a wound, a puncture, or a trauma.

In another embodiment, a chronic inflammation comprises a transplantrejection. Transplant rejection occurs when a transplanted organ ortissue is not accepted by the body of the transplant recipient becausethe immune system of the recipient attacks the transplanted organ ortissue. An adaptive immune response, transplant rejection is mediatedthrough both T cell mediated and humoral immune (antibodies) mechanisms.A transplant rejection can be classified as a hyperacute rejection, anacute rejection, or a chronic rejection. Chronic rejection of atransplanted organ or tissue is where the rejection is due to a poorlyunderstood chronic inflammatory and immune response against thetransplanted tissue. Also included in the term “transplant rejection” isa graft-versus-host disease (GVHD). GVHD is a common complication ofallogeneic bone marrow transplantation in which functional immune cellsin the transplanted marrow recognize the recipient as “foreign” andmount an immunologic attack. It can also take place in a bloodtransfusion under certain circumstances. GVHD is divided into acute andchronic forms. Acute and chronic GVHD appear to involve different immunecell subsets, different cytokine profiles, somewhat different hosttargets, and respond differently to treatment.

In another embodiment, a chronic inflammation comprises a Th1-mediatedinflammatory disease. In a well-functioning immune system, an immuneresponse should result in a well balanced pro-inflammatory Th1 responseand anti-inflammatory Th2 response that is suited to address the immunechallenge. Generally speaking, once a pro-inflammatory Th1 response isinitiated, the body relies on the anti-inflammatory response invoked bya Th2 response to counteract this Th1 response. This counteractiveresponse includes the release of Th2 type cytokines such as, e.g., IL-4,IL-5, and IL-13 which are associated with the promotion of IgE andeosinophilic responses in atopy, and also IL-10, which has ananti-inflammatory response. A Th1-mediated inflammatory disease involvesan excessive pro-inflammatory response produced by Th1 cells that leadsto chronic inflammation. The Th1-mediated disease may be virally,bacterially or chemically (e.g. environmentally) induced. For example, avirus causing the Th1-mediated disease may cause a chronic or acuteinfection, which may cause a respiratory disorder or influenza.

In another embodiment, a chronic inflammation comprises a chronicneurogenic inflammation. Chronic neurogenic Inflammation refers to aninflammatory response initiated and/or maintained through the release ofinflammatory molecules like SP or CGRP which released from peripheralsensory nerve terminals (i.e., an efferent function, in contrast to thenormal afferent signaling to the spinal cord in these nerves). Chronicneurogenic inflammation includes both primary inflammation and secondaryneurogenic inflammation. As used herein, the term “primary” neurogenicinflammation refers to tissue inflammation (inflammatory symptoms) thatis initiated by, or results from, the release of substances from primarysensory nerve terminals (such as C and A-delta fibers). As used herein,the term “secondary” neurogenic inflammation” refers to tissueinflammation initiated by non-neuronal sources (e.g., extravasation fromvascular bed or tissue interstitium-derived, such as from mast cells orimmune cells) of inflammatory mediators, such as peptides or cytokines,stimulating sensory nerve terminals and causing a release ofinflammatory mediators from the nerves. The net effect of both forms(primary and secondary) of chronic neurogenic inflammation is to have aninflammatory state that is maintained by the sensitization of theperipheral sensory nerve fibers. The physiological consequence of theresulting chronic neurogenic inflammation depends on the tissue inquestion, producing, such as, e.g., cutaneous pain (allodynia,hyperalgesia), joint pain and/or arthritis, visceral pain anddysfunction, pulmonary dysfunction (asthma, COPD), and bladderdysfunction (pain, overactive bladder).

EXAMPLES

The following non-limiting examples are provided for illustrativepurposes only in order to facilitate a more complete understanding ofthe disclosed subject matter. These examples should not be construed tolimit any of the embodiments described in the present specification,including those pertaining to the pharmaceutical compositions, methodsof preparing pharmaceutical compositions, or methods or uses of treatinga chronic inflammation or disease associated with chronic inflammation.

Example 1 Differential Scanning Calorimetry

This example illustrates formulation of solid solution pharmaceuticalcomposition as disclosed herein comprising a therapeutic compound.

To prepare a solid solution pharmaceutical composition disclosed hereinthe following general procedure was used. All ingredient, except theroom temperature solid lipid, were mixed together. This mixture washeated to a temperature in the range about 50° C. to about 60° C. withstirring in order to dissolve the therapeutic compound thereby creatinga solution. The room temperature solid lipid was then added to thesolution and the mixture stirred until incorporated. The mixture wasthen allowed to solidify by cooling to room temperature. Representativeformulations containing various therapeutic compounds are show in Table1.

The mixture was then allowed to solidify by cooling to room temperature.Solidified compositions were then assessed by appearance and byDifferential Scanning Calorimetry (DSC).

During the course of the analysis using DSC, a general trend wasobserved where a formulation which solidified with a cloudy appearanceformed a classic solid composition having a crystalline structure whileone which solidified with a clear appearance suggested a solid solutioncomposition having an amorphic structure. Additionally, solidifiedcompositions with a clear appearance that were then remelted with noappearance of a precipitate where indicative of a solid solutioncomposition having an amorphic structure.

Using the visual appearance and remelt assays, large numbers offormulations was accessed for the ability to for a solid-solutioncomposition. A formulation that failed to form a solid, or formed asolid with a cloudy appearance were not further analyzed and discarded.Similarly, formulations were not further analyzed and discarded if aprecipitate formed after remelting of a solidified compositions with aclear appearance. Formulations that formed a clear solid were alsosubsequently analyzed by DSC.

Data for representative ibuprofen formulations solidifying with a clearappearance are shown in FIG. 1. The DSC analysis revealed thatindividual components exhibited sharp, well-defined peaks. For example,ibuprofen possessed a well-defined melting point range of 75° C. to 78°C. (FIG. 1A). Similarly, a room temperature solid lipid, or hard fat,like GELUCIRE®43/01 had a well-defined melting point range of 41° C. to45° C. (FIG. 1B). These sharp, well defined melting point temperatureranges are indicative of a composition in a classic solid transitionphase having a well-defined crystalline structure. MAISINE™ 35-1 and PEG400 are liquids at room temperature, and as such has a melting pointbelow 20° C. For example, MAISINE™ 35-1 has a melting point temperaturerange of about 14° C. to about 16° C. and PEG 400 has a melting pointtemperature range of about 4° C. to about 8° C.

Unexpectedly, when a vehicle comprising a room temperature solid lipid(hard fat), a room temperature liquid lipid and a stabilizing agent wereexamined by DSC, a new melting point temperature peak appeared. Forexample, in addition to the GELUCIRE®43/01 peak of 41° C. to 45° C., DSCanalysis identified a new broad melting point temperature range of about32° C. to about 38° C. (FIG. 1C). This temperature range was differentthan that for the individual components alone: 41° C. to 45° C. forGELUCIRE®43/01, 14° C. to 16° C. for MAISINE™ 35-1, and 4° C. to 8° C.for PEG 400. These results indicate that a portion of the compositionwas forming into a solid solution phase instead of a classic solidphase.

Surprisingly, formulation comprising the therapeutic compound with thisvehicle exhibited a broad melting range with a melting point temperaturedifferent than the individual components (FIGS. 1D-1H). Furthermore, nopeaks relating to either the therapeutic compound alone or the hard fatalone were detected. For example, ibuprofen has a melting pointtemperature range of 75° C. to 78° C., GELUCIRE® 43/01 had a meltingpoint of 41° C. to 45° C., MAISINE™ 35-1 has a melting point temperatureof 14° C. to 16° C., and PEG400 has a melting point temperature of 4° C.to 8° C. However, a formulation comprising these components results in acomposition with a melting point of between 35° C. to 40° C., dependingon the amounts and ratios used. In a classic mixed phase of distinctsolid components, each individual peak would have been resolved, i.e.,75° C. to 78° C. for Ibuprofen, 41° C. to 45° C. and GELUCIRE® 43/01.This was not the case, these peaks disappeared altogether. The presenceof a single new melting point peak, and the concomitant disappearance ofthe individual component melting point peaks, for the solidifiedcomposition indicates that a novel solid solution structure oftherapeutic compound and room temperature solid lipid (hard fat) wasformed.

About2.03 g GELUCIRE® 43/01 (Gattefosse), a waxy solid (as room temperaturesolid lipid) having a melting point of between 41° C. to 45° C. andcomprising a mixture of saturated C₁₀-C₁₈ triglycerides, was added tothis solution and stirred until incorporated. The heated mixture wasthen cooled to about 37° C. to about 40° C., and aliquoted by pouringinto molds and cooled to room temperature. Alternatively, the mixturecan be cooled to room temperature and then subsequently reheated toabout 40° C. to about 45° C. for aliquoting into molds. The formulationsolidified with a clear appearance and remelted without forming aprecipitate. These results indicate that a solid solution formulation asdisclosed herein comprising Telmisartan was formed.

To prepare a solid solution pharmaceutical composition disclosed hereinusing Telmisartan, the following method was performed. About 160.2 mgTelmisartan, about 1.0 mL MAISINE™ 35-1 (Gattefosse), a glycerylmonolinoleate (as room temperature liquid lipid), and about 1.0 mLabsolute ethanol (as stabilizing agent) were added to a vessel andheated to about 50° C. to about 60° C. with stirring until allcomponents of the mixture were dissolved. About 2.03 g GELUCIRE®43/01(Gattefosse), a waxy solid (as room temperature solid lipid) having amelting point of between 41° C. to 45° C. and comprising a mixture ofsaturated C₁₀-C₁₈ triglycerides, was added to this solution and stirreduntil incorporated. The heated mixture was then cooled to about 37° C.to about 40° C., and aliquoted by pouring into molds and cooled to roomtemperature. Alternatively, the mixture can be cooled to roomtemperature and then subsequently reheated to about 40° C. to about 45°C. for aliquoting into molds.

This temperature range was differentthan that for the individual components alone: 41° C. to 45° C. forGELUCIRE®43/01 (Gattefosse) and 261° C. to 263° C. for Telmisartan.MAISINE™ 35-1 and absolute ethanol are liquids at room temperature, andas such both have melting points below 20° C. These results indicatethat a solid solution formulation as disclosed herein comprisingTelmisartan was formed.

Example 17 Macrophage Uptake Experiment

This example illustrates that a solid solution pharmaceuticalcomposition disclosed herein preferentially targets a therapeuticcompound to the immune system.

Cultures of U937 monocyte cell line were grown in RPMI-1640 supplementedwith 10% fetal calf serum (FCS) until the cells reached 90% confluentmonolayer. These cells were then treated with PMA and incubated in a 37°C. incubator under 5% carbon dioxide until the cells differentiated intomacrophages. Monolayers of macrophages were washed with fresh medium andthen 3 mL of one of the following test solutions were added: A) solidsolution formulation as disclosed herein comprising ibuprofen, GELUCIRE®43/01 (Gattefosse), MAISINE™ 35-1 (Gattefosse), and PEG 400; B) liquidformulation disclosed herein comprising ibuprofen, rapeseed oil andethanol; C) ibuprofen free acid; and D) vehicle with no therapeuticcompound. After incubation for 45 minutes the test solution supernatantswere removed and saved for analysis, and the cells were then washed inPBS several times and lysed using two cycles of freeze-thawing.Therapeutic compound concentration present in the test solution, testsolution supernatant, and cell lyste fractions was measured by HPLC. Thepercentage therapeutic compound taken up by the macrophages wascalculated using the following formula: % therapeutic compoundadsorbed=100×(compound mass recovered from cell lysate)/(compound massdelivered in test solution−compound mass recovered from test solutionsupernatant). Results are shown in the Table 1 below. These resultsindicate that mean uptake of a therapeutic compound by macrophageincrease 550% or more using the formulations of the pharmaceuticalcompositions presently claimed relative to compositions not formulatedin this manner.

Example 18 Animal Model for Intestinal Erosion

To assess whether a pharmaceutical composition disclosed herein reducedgastric irritation, experiments were conducted using an intestinalerosion murine model.

Sprague-Dawley rats were divided into seven experimental groupscontaining five animals each. After fasting overnight, the animals werechallenged with one with one of seven different treatments. Group A wasa control in which each mouse was orally administered 1%methylcellulose/0.5% polysorbate 80 vehicle only. Group B was a controlin which each mouse was orally administered solvent/adjuvant vehicleonly (gavage of 10% ethanol and 90% linseed oil). Group C was a controlin which each mouse was orally administered 150 mg/kg aspirin. Group Dwas a control in which each mouse was orally administered 100 mg/kgibuprofen suspended in 1% methylcellulose/0.5% polysorbate 80. Group Ewas the experimental group in which each mouse was administered apharmaceutical composition disclosed herein (BC1054-100) comprising 100mg/kg of ibuprofen, 10% ethanol, and 90% linseed oil. Group F was acontrol in which each mouse was orally administered 100 mg/kg ibuprofensuspended in 1% methylcellulose/0.5% polysorbate 80. Group G was theexperimental group in which each mouse was administered a pharmaceuticalcomposition disclosed herein (BC1054-200) comprising 200 mg/kg ofibuprofen, 10% ethanol, and 90% linseed oil. Animals were sacrificed 4hours after treatment and the stomachs were examined for degree ofhemorrhage and severity of mucosal erosive lesions. Gastric irritationwas scored as follows: 0, no lesions; 1, hyperemia; 2, one or two slightlesions; 3, more than two slight lesions or severe lesions; and 4, verysevere lesions. A score of 50% or more relative to Group C(aspirin-treated control group), which was set to 100%, was considered apositive score for gastric irritation.

Results are shown in Table 4. Group D (100 mg/kg of ibuprofen-treatedcontrol group) and Group F (200 mg/kg of ibuprofen-treated controlgroup) produced gastric lesions that were 75% and 95%, respectively,severe as those induced by Group C (aspirin-treated control group).However, Group E (BC1054-100-treated experimental group) and Group G(BC1054-200-treated experimental group) produced gastric lesions thatwere 20% and 40%, respectively, as severe as those associated with GroupC (aspirin-treated control group). These results demonstrate that that apharmaceutical composition disclosed herein reduced the extent to whicha therapeutic compound may cause mucosal lesions and cause gastricirritation.

Example 19 Animal Model for Inflammatory Bowel Disease

To assess the effectiveness of a pharmaceutical composition disclosedherein in treating an inflammatory bowel disease, experiments wereconducted using a TBS-induced colitis murine model.

C57Bl/6 male mice (6-7 weeks old) were divided into seven experimentalgroups containing at least ten animals each. On day 0, colitis wasinduced in mice from Groups B-G by intrarectal administration of 100 μLof TNBS (4 mg) in 50% ethanol under isoflurane anesthesia. Animals weredosed either once or three times a day from day −1 to day 5 with one ofseven different treatments. Group A was a control in which each mousewas orally administered ethanol vehicle only. Group B was a control inwhich each mouse was orally administered 1% methylcellulose vehicleonly. Group C was a control in which each mouse was orally administeredsolvent/adjuvant vehicle only (gavage of 10% ethanol and 90% linseedoil). Group D was a control in which each mouse was orally administered3 mg/kg of Prednisolone. Group E was a control in which each mouse wasorally administered 20 mg/kg of ibuprofen suspended in 1%methylcellulose (1 mL/kg) (no adjuvant). Group F was the experimentalgroup in which each mouse was administered a pharmaceutical compositiondisclosed herein (BC1054-20) comprising 20 mg/kg of ibuprofen, 10%ethanol, and 90% linseed oil. Group G was the experimental group inwhich each mouse was administered a pharmaceutical composition disclosedherein (BC1054-30) comprising 30 mg/kg of ibuprofen, 10% ethanol, and90% linseed oil. All animals were weighed daily and assessed visuallyfor the presence of diarrhea and/or bloody stool. On day 3 and on day 5colitis severity was assessed in all animals using video endoscopy,where images were taken and colitis severity scored visually by ablinded observer on a scale from 0 to 4 as follows: 0, normal; 1, lossof vascularity; 2, loss of vascularity and friability; 3, friability anderosions; and 4, ulcerations and bleeding. Following endoscopy on day 5,animals were sacrificed and the colon removed and its length and weightmeasured. Serum samples were obtained and the colon was fixed in 10%formalin. An additional piece of colon tissue was collected, weighed,and snap frozen in liquid nitrogen.

Results from these experiments are shown in Table 5. Group B(TNBS-treated control group) showed a statistically significantdifference in mean weight change when compared to Group A (untreatedethanol control group), all other group comparisons showed no differencein mean weight change. Group B (TNBS-treated control group) showed astatistically significant decrease in mean colon length when compared toGroup A (untreated ethanol control group). Additionally, Group D(Prednisolone-treated control group), Group F (BC1054-20-treatedexperimental group), and Group G (BC1054-30-treated experimental group)all showed a statistically significant increase in mean colon lengthwhen compared to Group B (TNBS-treated control group). Although Group B(TNBS-treated control group) showed a statistically significant increasein mean colon weight when compared to Group A (untreated ethanol controlgroup), all other group comparisons showed no difference in mean colonweight. With regards to the endoscopy colitis score, Group D(Prednisolone-treated control group) showed a statistically significantreduced mean colitis scores on both day 3 and day 5 when compared toGroup B (TNBS-treated control group). In a similar manner, both Group F(BC1054-20-treated experimental group) and Group G (BC1054-30-treatedexperimental group) showed a statistically significant reduced meancolitis scores on day 5 when compared to Group B (TNBS-treated controlgroup). These results indicate that a pharmaceutical compositiondisclosed herein was effective in treating an inflammatory boweldisease.

Example 20 Animal Model for a Systemic Arthritis

To assess the effectiveness of a pharmaceutical composition disclosedherein in treating arthritis, experiments were conducted using anα-collagen antibody induced arthritis (ACAIA) murine model that mimics asystemic arthritis like rheumatoid arthritis.

Male BALB/c mice were divided into eight groups, each containing 10animals. To induce arthritic symptoms, mice from all eight groups wereintravenously injected with 200 μL of an antibody solution comprising a2 mg cocktail of four α-collagen II monoclonal antibodies (ARTHRITOMAB™,MD Biosciences) on study day 0 (study commencement), followed by a 200μL intraperitoneal injection of a solution containing 100 μglipopolysaccharide (LPS) on study day 3. Each group was subjected dailyto a control or test treatment administered from day 0-11 as follows:Group 1 mice (1M) were treated orally with a vehicle preparationcontaining 1% methyl cellulose administered thrice daily; Group 2 mice(2M) were treated intraperitoneally with a positive control preparationcontaining 10 mg/kg etanercept (ENBREL®, Wyeth) administered once daily;Group 3 mice (3M) were treated orally with a 20 mg/kg test liquidformulation comprising ibuprofen and rapeseed oil (BC1054 LF-RO)administered once daily; Group 4 mice (4M) were treated orally with a 20mg/kg test liquid formulation comprising ibuprofen and rapeseed oil(BC1054 LF-RO) administered thrice daily; Group 5 mice (5M) were treatedorally with a 20 mg/kg test liquid formulation comprising ibuprofen anda glyceryl monolinoleate (MAISINE™ 35-1, Gattefosse) (BC1054 LF-MA)administered thrice daily; Group 6 mice (6M) were treated orally with a20 mg/kg test solid formulation comprising ibuprofen and theobroma oil(BC1054 LF-TO) administered thrice daily; Group 7 mice (7M) were treatedorally with a control preparation 1 comprising 20 mg/kg of ibuprofenadministered thrice daily; and Group 8 mice (8M) were treated orallywith a 20 mg/kg test solid formulation comprising ibuprofen and a waxysolid having a melting point of between 37° C. to 41° C. and comprisinga mixture of saturated C₁₀-C₁₈ triglycerides (GELUCIRE® 39/01,Gattefosse) (BC1054 LF-GE) administered thrice daily (Table 6). The doseadministered was calculated based on the assumption that each animalweighed, on average, 20 g. A fixed volume of 100 μL was administered toeach mouse, except those animals receiving the positive control (2M)were administered 200 μL.

Arthritic development and clinical examinations were monitored in allmice on study day 0 shortly before arthritis induction and subsequentlyon study days 3-7, 9, 10 and 12 (study termination). To access arthriticdevelopment, both an arthritis score and paw thickness (plethysmography)measurements were obtained. The arthritis score was based on visualassessment of arthritis reactions using a 0-4 scale in ascending orderof severity with Grade 0 indicating no arthritis reaction; Grade 1indicating mild, but definite redness and swelling of the ankle/wrist orapparent redness and swelling limited to individual digits, regardlessof the number of affected digits; Grade 2 indicating moderate to severeredness and swelling of the ankle/wrist; Grade 3 indicating redness andswelling of the entire paw including digits; and Grade 4 indicatingmaximally inflamed limb with involvement of multiple joints. Pawthickness was measured for both hind paws just above the foot pad andbelow the calcaneum using a dial caliper (Kroeplin, Munich, Germany).Mean values for paw thickness measurements were determined, and whereappropriate, analysis of the data by ANOVA with Tukey post hoc analysiswas applied to determine significance of treatment effects.

Clinical examinations included changes in body weight, condition ofskin, fur, eyes, mucous membranes, occurrence of secretions andexcretions (e.g. diarrhea), and autonomic activity (e.g. lacrimation,salivation, piloerection, pupil size, unusual respiratory pattern).Changes in gait, posture and response to handling, as well as thepresence of bizarre behavior, tremors, convulsions, sleep and coma werealso noted. Serum was collected at study termination.

Arthritis incidence increased in all groups from day 3. In Group 1Manimals incidence peaked on day 7 with 9/10 animals showing arthritisreactions which remained relatively constant until the end of the study.In Etanercept-treated Group 2M mice, incidence peaked on day 6 at 9/10animals showing signs, but had decreased to 1/10 by day 12. The peakincidence of arthritis in Group 3M and Group 4M animals receiving BC1054LS-RO once or thrice daily was on day 7 (9/10 and 7/10 animals,respectively), and this had decreased to 4/10 mice in both groups by day12. The arthritis incidence peaked on day 6 in the Group 5M animalsreceiving BC1054 LS-MA with 8/10 animals affected, and the incidencefluctuated with between 6 and 8 animals scoring until the end of thestudy. By day 6, 9/10 animals presented with arthritis in Group 6Manimals receiving BC1054 SF-TO, but this also fluctuated and ended at7/10 on day 12. In the Ibuprofen-treated Group 7M, the peak of arthritisincidence was recorded on day 6 with 8/10 animals affected, and thisremained relatively constant until the study termination. Group 8M micereceiving a BC1054 LS-GE exhibited peak incidence on day 6 with 9/10animals presenting with signs of arthritis, but this had decreased to4/10 by day 12.

Clinical signs associated with LPS-administration developed in allgroups following the LPS boost on day 3. These had disappeared in allgroups by day 12. No mortalities occurred during this study orsignificant differences in body weight between the vehicle-treated groupand test item-treated groups.

The results of mean paw thickness are given in Table 7. Mean rear pawthickness in Group 1M animals (vehicle-treated) was 1.72±0.01 on day 0.Thickness increased and peaked on day 9 at 2.33±0.15, and ended at2.17±0.11 on day 12. In Etanercept-treated Group 2M mice, mean rear pawthickness began at 1.70±0.02 on day 0. This increased, peaking at1.96±0.05 on day 6 before decreasing back to 1.77±0.02 on day 12.Etanercept treatment resulted in significantly decreased paw volumecompared to the positive control mice on days 9, 10 and 12. In Group 3M,which received BC1054 LS-RO once daily, rear paw thickness was 1.71±0.02on day 0. By day 7 the swelling in this group had peaked at 1.96±0.05where it remained relatively constant thereafter. There were significantreductions in the mean paw swelling on days 6 and 9 followingadministration of BC1054 LS-RO. The mean rear paw thickness in Group 4M,which received BC1054 LS-RO thrice daily, increased to 1.97±0.08 on day10 (from 1.70±0.03 on day 0), from day 10 paw volumes remained relativeconstant till the end of the study. BC1054 LS-RO thrice daily resultedin significantly reduced mean paw thickness compared to vehicle-treatedmice (Group 1M) on days 6, 7 and 9. Group 5M mice treated with BC1054LS-MA had peak paw volume at day 7 (1.97±0.05 from 1.69±0.02 on day 0),this group had significantly reduced measurements on day 6 and day 9when compared to the vehicle treated Group 1M animals. In Group 6Manimals treated with BC1054 LS-TO, mean rear paw thickness began at1.74±0.01 on day 0. This increased to a peak of 2.05±0.10 on day 7before decreasing back to 1.94±0.06 on day 12. No significantdifferences were recorded between BC1054 LS-TO-treated animals (Group6M) and those treated with vehicle control (Group 1M). In the groupwhich received Ibuprofen (Group 7M), rear paw thickness was 1.71±0.02 onday 0. By day 7 the swelling in this group had peaked at 2.15±0.10before decreasing to 2.02±0.08 on day 12. No significant differenceswere observed when this group was compared to the vehicle control Group1M. Group 8M animals treated with BC1054 LS-GE exhibited a slightincrease in rear paw thickness from 1.72±0.02 on day 0 to 1.85±0.06 onday 7, this remained relatively constant finishing at 1.77±0.03 on day12. Administration of BC1054 LS-GE resulted in significantly reduced pawswelling in animals (Group 8M) compared to vehicle controls (Group 1M)on days 6, 7, 9, 10 and 12.
